DEVICE AND METHOD FOR GENERATING CODED SIGNAL OR DECODING ENCODED AUDIO SIGNAL BY USING SITE WITH MULTIPLE OVERLAP Russian patent published in 2017 - IPC G10L19/25 H03M7/30 

FIELD: physics.

SUBSTANCE: device for generating an encoded signal comprises: a controller of the window sequence for generating information about the window sequence for framing an audio signal, wherein the information about the window sequence indicates the first window function for generating the first frame of the spectral values, a preprocessor for framing the second block of samples corresponding to the second window function and one or more third window functions, a spectrum converter for receiving the first and the second frames of the spectral values and for receiving the first and the second portions of the spectral values of the second frame, a processor for processing the first frame and the second frame to obtain encoded frames of an audio signal.

EFFECT: providing an improved concept of audio encoding, decoding, which provides an improved efficiency of the device.
